Donnay rackets offer better control and power, while being more comfortable than any other brand. This is due to the unique solid construction, the patented "Xenecore" technology.

Donnay is the only brand with High Density Foam material that fills the entire inside of the racket. Xenecore provides superior shock absorption and vibration absorption, not only preventing but and resulting in relief of chronic tennis elbow, shoulder or wrist injuries. Donnay can prove this effect with multiple studies and can therefore confidently recommend its rackets to all tennis players suffering from tennis elbow.

Donnay rackets have the lowest stiffness of any racket brand. The Allwood model has an RA of just 50, compared to Clash's published RA of 55. While Donnay rackets are soft, they still have more than enough power, due to their dynamic stiffness, which is made possible by the unique patented "Multiple Cores" design that no one else can duplicate. All other racket brands are made with a single graphite tube. Donnay rackets have up to 6 graphite tubes placed together to provide increased stability and prevent damage.
